The US Bancorp Tower business center is located in a landmark building standing tall on the Portland skyline. The largest class-A building in the city, this 43-story tower is known both for its striking architecture and as one of the Northwest's premier locations in Portland's central business district. It was built as the Oregon headquarters for the US Bancorp Bank and later received LEED-EB® Silver level certification for environmental performance. Views across the surrounding countryside, mountains and the Willamette River and bridges are breathtaking. Portland has been voted as the greenest city in America (American Business Journals) and ranked one of the best places for green jobs (Clean Edge research firm). It has a growing concentration of clean technology and green building firms as well as a diverse, stable base of leading employers in industries including apparel and creative services, electronics, advanced manufacturing and healthcare.
